IMPROVEMENT IN WINDOW-FRAMES.

Specification forming part of Letters `Patent No. 208,926, (latedOctober 15, 1878; application filed September 2, 1878.

To all whom it may concern:

Be it known that I, GnAs. REBHUN, of the borough of Butler and StateofPennsylvania, have invented a new and Improved Sash-Balance and WindowFrame to suit same, of which I believe the following to be a correctspecification My invention is an improvement in sashbalances; and hasfor its object to provide an arrangement, with weights, lines, andpulleys, that may be applied to windows constructed with solid frames tosave materials and labor, and prevent weakening the brick-workconsequent upon the use of ordinary box-frames.

It consists in providing a space in either frame-jamb, worked from theinside, sufficient to allow of a free movement of dat weights attachedto cords which pass over pulleys and support the window-sash, saidspaces being inclosed by means substantially as hereinafter set forth.

In my drawings, Figure l is a front elevation of window as seen from theoutside. Fig. 2 is a vertical transverse section. Fig. 3 is a plan orhorizontal section of the same.

Similar reference-letters indicate like partsl in all of the gures.

Referring to drawings, A is the frame of a window constructed in ageneral way as solid frames are made.

In the jambs of the fra-me are fashioned spaces B, with rabbet-bearingsa. Projections b are left about the middle of these spaces B, to serveas partitions to separate the spaces b', for the weights J, from eachother, and afford bearing-surfaces to flat strips C, fitted into a partof the spaces or recesses B. The strips C are formed of a length anddepth to fit between the sill and soffit of the window, and against therabbets and division-strips b, with their faces flush with the insidesurfaces of the jambs. The width ofthe strips C is less than the widthof the inside of spaces B, to admit the outer window-strips, D, whichare grooved, as shown,`to receive said strips.

The strips D, which represent the ordinary outside window-strips, beingextended and grooved to receive the tongues of the strips C, serve,together with the strips C, to inclose the space provided for theweights, and furnish an easy means of access to said weights when theyare to be placed in or removed from position.

Grooves E are formed in the faces of the strips O, to receive thevertical parting-beads.

The weights used in my frame are rectangular in horizontal section, anddat, with length greater than that of ordinary sash-weights.

Openings F are provided in the window-sills for the free passage of theweights should it be necessary to use them of extra length, in

order to have the sash raised to the soflit of' the window-frame.Ordinary cords or lines I, attached to the weights, pass over pulleys H.These pulleys are secured to the win do w-frame, against the walls whichform the outside of the frame, or rather against thesurfaces which formthe inside surface of the recesses provided for the weights J. The boxesinto which the pulley-axles bear when said pulleys are in positionproject inward toward the sash, and in order to have the said sash passfreely over the pulleys when raised to their greatest height I groovetheir vertical edges until said grooves reach the point where the cordsare secured.

I am aware ofthepatent of Hare, N o. 148,117, in which boxes forordinary weights are formed by cutting the jambs of the frame entirelythrough, and planting ilat strips, not flush, 011 the outside, andsimilar ones on the inside of vsaid frame, with divisions uniting saidstri ps,

and to such I make no claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The solid frame A, provided with spaces b' b for weights J J, incombination with strips G and D, all constructed and arranged asdescribed, for the purpose set forth.

OHAS. REBHUN.
